Compliance with the tolerance budget of applications: long-term aging must be taken into account
Each application has a tolerance budget in terms of frequency deviation that must be adhered to even in the worst case scenario in order to ensure that the application functions. Developers must therefore be aware of all factors that can lead to frequency deviations. The sum of all worst-case scenarios of these factors must not

Ask the Engineer: how temperature-sensitive are quartz crystals?
Nowadays, Christmas without quartz crystals is unimaginable! Why? Even the modern time switches for outdoor lighting need a quartz to have an accurate time base. Also, a lot of our gifts are based on state-of-the-art electronics. Cell phones, smartwatches, PCs – they all need highly accurate frequency giving components to communicate with each other. Without

What is the similarity between a quartz blank and a pillow?
Do you already know the similarity between a quartz blank and a pillow? Exactly! Both have the same shape. The so-called “bevelling” or “contouring” in the production process of quartz blanks results in the characteristic lens shape of quartz blanks. “This procedure is mainly used for ‘thicker’ blanks, which are in the low frequency range,

TCXO: How it works and why
A TCXO is a temperature-compensated crystal oscillator that is used whenever particularly high stability within a variant temperature environment is required, i.e. when the frequency deviation of the oscillator must be minimal over its entire operating temperature range. Oscillators using AT quartz crystal plates, so called “blanks”, are the most economical solution to create a

The Strengths of 32.768 kHz Oscillators
The boom of quartz watches in the 70s has shown: When it comes to precise time recording, there is nothing better than quartz crystals! This is no different today. Frequency control products with the characteristic frequency of 32.768 kHz can be found in almost all applications with integrated time measurement, e.g. laptops, mobile phones or

It’s All about the Angle – The AT-Cut for Quartz Crystals
Whether medical technology, telecommunications or consumer electronics, quartz crystals have established themselves as a precise frequency generator in all industries. When energized, the thin quartz disc oscillates at a steady rate and thus determines the heartbeat of the application. While this sounds simple, the matter is quite complex because quartz blanks are not all the
